We try to contact with vuplus some times but never receive answer from Vuplus. I don't know if other teams have support from vuplus or they release images because they buy their own boxes.
We only ask vuplus for drivers developers contact to report bugs and one sample to test images.
I don't know wich is the best way to pressure them because we don't know if the mail adress we sent requests is online.
We try again to contact with them or try to get an adress to send emails from users to pressure
